Evaluation of three commercial tick removal tools

Area of Science:

• Veterinary Entomology
• Parasitology
• Medical Entomology

Background:

• Tick-borne diseases pose significant risks to animal and human health.
• Proper tick removal is crucial to prevent pathogen transmission and minimize host tissue damage.
• Existing methods, such as tweezers, may be suboptimal for complete tick removal.

Purpose of the Study:

• To compare the efficacy of three commercial tick removal tools against standard medium-tipped tweezers.
• To assess the degree of tick damage and residual attachment cement post-removal.
• To evaluate the performance of tools on different tick species and life stages.

Main Methods:

• Three commercial tick removal devices and medium-tipped tweezers were tested.
• Inexperienced users removed attached American dog ticks (Dermacentor variabilis) and lone star ticks (Amblyomma americanum) from laboratory rabbits.
• Tick damage and attachment cement were quantified and compared across tools and tick types.

Main Results:

• All tested tools successfully removed adult American dog ticks and lone star ticks.
• Nymphal ticks were removed with damage by all tools; adult tick removal showed less damage.
• American dog ticks were generally easier to remove than lone star ticks, with fewer instances of retained mouthparts.

Conclusions:

• Commercial tick removal tools are effective for removing both adult and nymphal ticks.
• These tools demonstrate superior performance for nymphal tick removal compared to tweezers.
• Commercial tick removal tools represent a functional and viable alternative to tweezers for tick extraction.
